INTRAVASCULAR DELIVERY SYSTEM WITH CENTRALIZED STEERING
First Claim
Patent Images
1. A delivery system configured for delivery of an interventional device in an intravascular procedure, the delivery system comprising:
- a handle having one or more controls;
a delivery catheter having a proximal end and a distal end, the proximal end being coupled to the handle, the delivery catheter having a proximal section and a distal section,wherein at least the distal section is configured to selectively form a compound curve to enable positioning of the distal end relative to a targeted intravascular treatment site, andwherein the compound curve includes a first curve formable at a proximal portion of the distal section and a second curve formable at a distal portion of the distal section;
one or more control lines each operatively coupled to a control of the handle and each extending from the handle through a wall lumen of the delivery catheter toward the distal end; and
a distal coupler disposed at or near the distal end of the delivery catheter, the one or more control lines extending to the distal coupler and engaging with the distal coupler such that tensioning of the one or more control lines changes position of the distal coupler to thereby form or adjust the compound curve.

Abstract
The present disclosure describes delivery systems for intravascularly delivering one or more interventional devices to a targeted treatment site within a patient'"'"'s body. A proximal end of a delivery catheter is coupled to a handle. One or more control lines extend from the handle through the delivery catheter to a coupler disposed at or near the distal end of the delivery catheter. Tensioning of the one or more control lines manipulates the coupler to form or adjust a compound curve in the delivery catheter.

17. A delivery system configured for delivery of an interventional device in an intravascular procedure, the delivery system comprising:
-
a handle having one or more controls; a delivery catheter having a proximal end and a distal end, the proximal end being coupled to the handle, the delivery catheter having a proximal section and a distal section, wherein at least the distal section is configured to selectively form a compound curve to enable positioning of the distal end relative to a targeted intravascular treatment site, wherein the compound curve includes a first curve formable at a proximal portion of the distal section and a second curve formable at a distal portion of the distal section, the first and second curves being formable in different planes, wherein the first curve is pre-curved to an angle of about 30 to about 80 degrees and is configured to be further bendable to an angle of about 70 to about 120 degrees, and wherein the second curve is pre-curved to an angle of about 5 to about 30 degrees and is configured to be further bendable to an angle of about 10 to about 50 degrees; one or more control lines each operatively coupled to a control of the handle and each extending from the handle through a wall lumen of the delivery catheter toward the distal end; and a distal coupler disposed at or near the distal end of the delivery catheter, the one or more control lines extending to the distal coupler and engaging with the distal coupler such that tensioning of the one or more control lines changes position of the distal coupler to thereby form or adjust the compound curve.

18. A method of delivering an interventional device intravascularly to a targeted treatment area, the method comprising:
-
providing a delivery system comprising; a handle having one or more controls; a delivery catheter having a proximal end and a distal end, the proximal end being coupled to the handle, the delivery catheter having a proximal section and a distal section, wherein at least the distal section is configured to selectively form a compound curve to enable positioning of the distal end relative to a targeted intravascular treatment site, and wherein the compound curve includes a first curve formable at a proximal portion of the distal section and a second curve formable at a distal portion of the distal section; one or more control lines each operatively coupled to a control of the handle and each extending from the handle through a wall lumen of the delivery catheter toward the distal end; and a distal coupler disposed at or near the distal end of the delivery catheter, the one or more control lines extending to the distal coupler and engaging with the distal coupler such that tensioning of the one or more control lines changes position of the distal coupler to thereby form or adjust the compound curve; routing the distal end of the delivery catheter to the targeted treatment site; and delivering the interventional device through a lumen of the delivery catheter. - View Dependent Claims (19, 20)
